can someone please help me. this is extremely frustrating.

Answer 1

In 1 we have -1=<...
In 2 we have 2>=...
d={2,1,0,-1}
__________________________________________________________________
In 1 we have 0=<...
In 2 we have -2=>...
K = {2,0,1}
__________________________________________________________________
y = {0,1,2,3,4,5,...,12}
___________________________________________________________________
x = { }
_____________________________________________________________________
In 1 we have 3=<
In 2 we have 0=>...
So we cant give the numbers from both of them and we have :
x = { }

End !:)
Understand ?!
